When you think about math, you probably don’t think about breaking the law, solving mysteries or finding criminals. But a mathematician in Maryland does, and he has come up with mathematical tools to help police find criminals.
People who solve crimes look for patterns that might reveal (揭示) the identity of the criminal. It’s long been believed, for example, that criminals will break the law closer to where they live, simply because it’s easier to get around in their own neighborhood. If police see a pattern of robberies in a certain area, they may look for a suspect who lives near the crime scenes. So, the farther away from the area a crime takes place, the less likely it is that the same criminal did it.
But Mike O’Leary, a mathematician at Towson University in Maryland, says that this kind of approach may be too simple. He says that police may get better clues to the location of a criminal’s home base by combining these patterns with a city’s layout (布局) and historical crime records.
The records of past crimes contain geographical information and can reveal easy targets — that is, the kind of stores that might be less difficult to rob. Because these stores are along roads, the locations of past crimes contain information about where major streets and intersections are. O’Leary is writing a new computer program that will quickly provide this kind of information for a given city. His program also includes information about the people who live in the city, and information about how a criminal’s patterns change with age. It’s been shown, for example, that the younger the criminal, the closer to home the crime.
Other computer programmers have worked on similar software, but O’Leary’s uses more math. The mathematician plans to make his computer program available, free of charge, to police departments around the country.
The program is just one way to use math to fight crime. O’Leary says that criminology — the study of crime and criminals — contains a lot of good math problems. “I feel like I’m in a gold mine and I’m the only one who knows what gold looks like,” he says. “It’s a lot of fun.”

“Tomorrow is another day”---- this line has impressed various people at various times. It's now 70 years after it appeared in the film, but it still seems to hold its power especially during an economic downturn.

The phrase comes from a film adaptation of Margaret Mitchell's successful 1936 novel Gone With the Wind. It's set in the American South and tells the story of a strong heroine, Scarlett O' Hara, who struggles to find love during the Civil War and, afterwards, of her strength in surviving the war and its hardships.

Love story 

In a moment of despair, Scarlett finally realizes that her love belongs to Rhett Butler. For many audiences, it is the theme of love and struggle that has kept the movie alive. While the burning of Atlanta might seem irrelevant to today's viewers, the timeless theme of love keeps its ability to touch people.

With a promise to her lover still in her mind, Scarlett chooses to stay in the midst of war and take care of Melanie. But her heart is broken when Rhett just walks away, leaving the woman that he once loved with cruel words, "Frankly, dear, I don' t give a damn."

Great epic

The film shows the love-hate relationship of these characters, but also American history, the fall of the Confederacy and the following period of Reconstruction in the South. The background made this film a true classic in the epic genre.

When the film opened after World War II, French viewers loved it, and it reminded them of their fight against the Nazis. In 1940 Shanghai, during the War of Resistance Against Japanese Aggression, people stood in line for hours to watch this film, and saw the same suffering they were having as well as the hope and possibility of building a new homeland from the ruins.

Each nationality could identify with the story and see it as a victory. In fact, Gone With the Wind never lost its charm and ability to inspire and amaze.

Biggest of all time

The film had five directors, 15-plus screenwriters, and an unexpected $3.9 million budget. The film brought in $ 200 million, which makes it the biggest selling film of all times in North America. It also won 10 Academy awards in 1940.

1.The underlined "it" in the first paragraph refers to _______.

2.The text is written mainly to _______.

3.It can be concluded that Scarlett O' Hara is _______.

4.The passage mentions Shanghai in order to _______.

If you ask some people, “How did you learn English so well?” you may get a surprising answer: “In my sleep!”
These are people who have taken part in one of the recent experiments (实验) to test “the learn while you sleep” method (方法), which is now being tried in several countries, and with several subjects. English is among them.
Scientists say that this sleep study method greatly speeds language learning. They say that the ordinary person can learn two or three times as much during sleep as in the same period during the day—and this does not affect (影响) his rest in any way. However, sleep teaching will only put into your head what you have studied already while you are awake.
In one experiment, ten lessons were broadcast over the radio for two weeks. Each lesson lasted twelve hours — from 8 p.m. to 8 a.m. The first three hours of English grammar and vocabulary (词汇) were given with the students awake. At 11 p.m. a lullaby (催眠曲) was broadcast to send the student to sleep and for the next three hours the radio in a soft and low voice broadcast the lesson again into his sleeping ears. At 2 a.m. a sharp noise was sent over the radio to wake the sleeping student up for a few minutes to go over the lesson. The soft music sent him back to rest again while the radio went on. At 5 o’clock his sleep ended and he had to go through the lesson again for three hours before breakfast.
【小题1】In the experiment, lessons were given____ .

Computer programmer David Jones earned $ 150,000 a year designing new computer games, yet he cannot find a bank prepared to let him have a check card (信用卡). Instead, he has been told to wait another two years until he is 18.

He works for a small firm in Liverpool, where most young people of his age are finding jobs. David”s biggest headache is what to do with his money. Though he has high payment, he cannot drive a car, or get credit cards.(信用卡)

David got his job four months ago, a year after leaving school with six O-Levels(普通成绩) and working for a time in a computer shop. “I got the job because the people who run the firm knew I had already written some programs,” he said.

“I suppose $150,000 sounds a lot but I hope it will come to more than that this year.” He spends some of his money on records and clothes, and gives his mother $20 a week as he lives with his parents. But most of his spare time is spent working.

“Unfortunately, computing was not part of our studies at school,” he said. “ But I had been studying it in books and magazines for four years in my spare time. I knew what I wanted to do and never considered staying on at school. Most people in this business are fairly young, anyway. I would like to earn a million and I suppose early retirement(退休) is a possibility. You never know when the market might disappear.

11. why is David so different from other young people of his age?

A .He has got a job.                                      B. He lives at home with his parents

One Christmas Eve, my husband made his way home from work.  36 , he worked the entire day but let his stuff go  37  so that they could be with their families.
He drove down the street and made the  38  towards our home. On one side of the road, an old man stood, drenched to the bone (被雨淋得湿透了), with his hand  39 . The rain had been  40  heavily that day. My husband stopped, and asked him where he was  41 . He wanted to go about five miles past our home, but my husband still told him to  42 . My husband chatted with him, drove  43  our house and took him home for his Christmas Eve.  44  turned out that this poor man was what we now  45  as a “slow learner” and the only job he could get to  46  him and his elderly mother was at the bakery near where my husband worked. He worked from 5 a.m. until 1 o’clock in the  47 . Not only that, but that poor man had been standing there trying to get a ride on Christmas Eve for about 5 hours  48  my husband picked him up.  49  else would give him a ride because they didn’t want to get their seats  50 .
Over the years my husband  51  to give him a ride home whenever he saw him trying to get a ride. When he passed  52 , my husband went to his funeral.  53  my husband didn’t know his family, they knew of him. Even his twin sister who  54  in the state of Washington knew who my husband was and everyone thanked him for his  55  toward one who had so little.
An act of kindness can make another person’s day, or even their life.
